Abstract

We study the partition norm—the product of the parts of a partition—with emphasis on partitions whose parts all exceed 1. We obtain two bivariate recurrences for the sum of norms over partitions into distinct parts, including a refinement that separates the contributions of the part 1 and of the prime 2. To count partitions of n with parts greater than 1 having norm i, we introduce the restricted norm-counting function r_{>1}(i,n), give its two-parameter generating function, and derive recurrences and other relations. Finally, we formulate analogues of Goldbach’s and twin-prime conjectures in the language of partition norms.
